摘要： A design structure embodied in a machine-readable medium used in a design process may include a system for detecting a fault in a signal transmission path. Such system may include, for example, a hysteresis comparator including a latch having n-type field effect transistor (“NFET”) storage elements. The hysteresis comparator may be operable to detect a crossing of a reference voltage level by an input signal arriving from the signal transmission path such that when the comparator does not detect an expected crossing of the reference voltage level by the input signal, the fault is determined to be detected in the signal transmission path.

摘要： Digital testing of an analog driver circuit is enabled using a circuit including a control circuit for generating signals, a differential driver circuit for receiving a differential input signal, amplifying the differential input signal and transmitting a differential output signal, a programmable termination impedance circuit for generating a differential termination impedance at the output node of the differential driver circuit, and a differential receiver circuit for converting the differential output signal to a single ended signal and transmitting the single ended signal. The testing includes skewing a differential output termination impedance, adjusting a differential receiver circuit voltage offset, selecting a differential driver circuit power level, enabling a decoder which activates only one differential driver circuit segment per test sequence, activating a segment, stimulating the differential driver circuit with digital test patterns, receiving differential driver circuit output, converting the output to a single-ended signal, and observing the single-ended signal.
